THE PERMEABILITY OF HIGH STRENGTH BLAST FURNACE SLAG CONCRETE

The permeability properties of the high strength slag concrete were studied by means of carbonation tests, water suction and gas penetration. The permeability of the blended cement concrete was compared to that of the alkali activated slag concrete and Portland cement concrete. According to the results the high strength slag concrete activated by cement is very dense. The carbonation results indicated that in high strength concrete the dense structure of the paste compensates for the lack of calcium in blended cement concrete. In the alkali activated slag concrete the structure contains microcracks at the microscopic level. The rate of carbonation was significantly higher in alkali activated slag concrete than in other concretes. The gas permeability results revealed the same tendencies as the carbonation tests. Water suction values were very low in all high strength concrete samples. (A) For the covering abstract see IRRD 851601.
